Recruiting Co-Pilot | Y Combinator

An open-source AI recruiting assistant — the one we use to hire at YC.
Recruiting is one of the hardest things you do as a founder, and the only way to get good at it is to genuinely connect with people — to understand what motivates them, what they're good at, and whether what you're building is actually a fit.
We've learned a lot about hiring by watching and helping thousands of YC companies do it, and we wanted to get that same leverage ourselves. So we codified the best practices of running a recruiting process into a set of Claude Code skills, wired up to Work at a Startup, Gmail, Calendar, and our ATS.
We use it every day on the YC software team: you talk to it in plain English and it handles the operational work — triage, outreach, follow-ups, scheduling, and keeping the whole pipeline in sync across systems. You still have to find great people, interview them well, and convince them to join you — that's the hard part. But this set of skills can do a lot of the operations (and even sourcing) for you.
Building this tool — and open sourcing it — is the kind of work we do here on YC software. It's a tool that provides tremendous leverage for our founders, and was inspired by how they work each day. We have no PMs and no designers, so every engineer owns their problem and the solution end-to-end. And suffice to say, we're deeply AI pilled, and we hope you are too.
You'd build software that thousands of startups depend on, work with 20 years of startup data, and stay close to founders at batch events, Demo Day, and dinners. If that sounds like your kind of work, we're hiring software engineers — come build the software behind YC.
